Title: Handy-type recorder
Inventor: YAMAGATA KIYOHIRO
IPC: B41J3/28
Filed: 1986-03-14
Abstract: PURPOSE:To obtain a handy-type recorder small in size and having excellent operability and high accuracy, by separating a recording position detecting part for generating a recording timing signal into a magnetic sensor and a magnetic sheet. CONSTITUTION:As a main body 1 is manually scanned in a direction perpendicular to the boundary between an S pole and an N pole of a magnetic sheet 4 laid on the lower side of a recording material 3, a variation in a magnetic force is detected by a magnetic sensor 6, which generates an output according to a magnetization pitch. The output from the sensor is shaped to be a rectangular wave by a wave-shaping circuit 12, and an edge of the rectangular wave constitutes a recording timing signal 13, which is sent to an external device 14. Then, a recording signal previously accumulated in the external device 14 is outputted to a driving circuit 16 as a recording signal 15 according to the recording timing signal 13, whereby a recording head 5 is driven to record desired images on the recording material 3 by dot matrices. Accordingly, accuracy of recording positions is enhanced.
